Patterns of alcohol use and response to digital brief interventions in college students: a secondary analysis of a cluster randomized trial.

ABSTRACT:

Background

Drinking among college students in India is rising, influenced by social and cultural shifts. This study aimed to classify drinking behaviors among underage students using Latent Class Analysis (LCA) and assess the effectiveness of digital screening and brief intervention (DSBI) and brief advice (DSBA) across identified classes.
